Hundreds of fans lined up outside of the venue more than an hour before show time to try to get into the invitation-only concert. Tickets were also given away through social media sites and fans not who didn’t manage to win them could watch the show through a livestream on Pepsi.com.

Gloriana, set to release its second album “A Thousand Miles Left Behind” today, wanted to participate in the show so badly that the band flew into Nashville from New York City on Monday for the night. Today, the band members must turn around and fly back to the Big Apple to continue their media blitz in promotion of the new album. They’ll be on "Fox & Friends" later this week.

“We started our day (Monday) at 4 a.m. when we went to ‘Good Morning America,’” Gloriana’s Rachel Reinert said on Monday night before the concert. “It’s a very busy week but we’ve been really looking forward to (releasing the album) for a really long time. With the song ‘(Kissed You) Good Night’ at No. 2, it couldn’t be better timing.”

The trio acknowledged it was a bit of a hustle to get back to Nashville in time to play the show, but Reinert said they didn’t see a reason not to make it work.

“We love Billboard and not only do we love Billboard, we love Pepsi,” quipped Gloriana’s Tom Gossin. “It’s the choice of a new generation.”

Kramer, whose song “Why Ya Wanna” is approaching Top 10 on Billboard’s Hot Country Songs chart, also cited her love of Billboard as why she wanted to come out and participate in the show.

“Billboard is a vital part of my career,” Kramer said. “Their support has been phenomenal. Anything I can do to help them (I will) and it’s fun to feel like you’re supported."

As for what the 900 fans in attendance should expect, Kramer said: "We’re a rocking little band, but fans will hear a lot of songs off the album and one cool cover I love to do.”

The show was part of a series that also featured Katy Perry in concert in California. A third installment is set for New York, although the performers for that event have yet to be announced.
